I've been doing something like this for the past year or so, I just have a Google doc called "Workflow". If I encounter an error or problem I've never seen before, I write the error down, and then the solution (with links if appropriate). Bold the ones I never solved or had to work around. Put eureaka moments in italics (oh THATS how it works!?). It helped me a lot because I would stumble around before that remembering I had this same error or problem a few weeks or months before, but could not remember how I solved it. I'm much more productive and it's cool seeing a list of all the things I've solved. Also, when multiple days go by without and entry you feel really really good.
